The easiest way to replace a lost manual for an alarm keypad is to visit the manufacturer's website and download a new copy. Alarm equipment companies such as Honeywell, ADT and GE Security all make their user's manuals available through their websites.
Determine which firm made the keypad, and then visit its website. For example, if it is a Honeywell wireless keypad, begin the search at Honeywell's security alarm page, Security.Honeywell.com. Next, click on the "products" tab, and select "keypads" from the drop-down menu. The keypads page narrows the hunt further, with products classified by type: graphic touch screen, wired, voice, wireless and receivers. Choose the applicable category, in this case "wireless."
Clicking on the "wireless" header leads to a selection of three wireless Honeywell keypads: 828V - Wireless Fixed English Voice Keypad, 5828 - Wireless Fixed English Keypad and 5839 - Wireless Alpha keypad. If the 5828 is the keypad in question, click on its name. A new page just for that model appears, with options to learn more about the product description, its features, documentation and ordering information. Click on the "documents" tab, and a list of all available literature appears, including the user's guide.
The literature available on these firms' websites is, generally speaking, in .pdf form. The free Acrobat Reader makes it easy to open and read these documents.
